Compared it to a much more expensive (accurate and regularly calibrated) scale and this one is 5-7 lbs low. Contacted Feather River and they said that you cannot really compare their scale to others, what ever that means. They are willing to check it out however but, for the price to ship to them and back it isn't worth it. Save your money and buy something better.

seems to work well for me. My bow was checked at bow shop by easton digital scale at 67 pounds. This told me 67 pounds. sometimes you need to draw it a few times and kind of take the average but it will get you really close for sure
